How can i merge hundreds or even thousands of video files into one using ffmpeg or any other tools?

Question

Basically i have like hundreds of small video files (format is .ts) and each of them is like only 10 seconds long and about 10MB size. They are named in order like '100.ts' '101.ts' '102.ts' ... '600.ts' (names usually dont start from 1), so how can i merge them into 1 big file (and transfer it to mp4 format hopefully as well) using ffmpeg or any other tools? oh also i need to do that in Windows environment, thanks

Answer 1

Use the concat input format:

First create a text file like

file "100.ts"
file "101.ts"
...

and save it as "merge.ffconcat".

Now use ffmpeg -f concat -i "merge.ffconcat" [your codec options here] -f mp4 output.mp4 to merge and if necessary reencode.
